Inspection Time for my 1996 850 Volvo, but a problem here......

I took it to my mechanic and he turned off my engine light, and he told me I have to drive alot, so when he sets the monitor in between my front seats, there are some codes that are not done yet, I have two codes left to be done. I have been doing alot of driving and my mechanic has turned off the check engine light twice, and i need to get my inspection asap, please help me.

The information below was complied by me, it explains what causes the check engine light to come on and the process of finding the cause.

When the Check Engine light (or Service Engine Soon) is turned on, the systems computer control unit (called the PCM) has sensed a fault in the electronic controls of the engine and/or the emission system. When this happens you will seldom feel the car engine run any different. There are about 200 possible system faults (the gas cap is just one of them) that turn the Check Engine light on, to know what has developed a problem you must have the system tested, this is called an OBD2 fault code test, Kragen/Oriley and Autozone parts stores (USA only) do this testing for free.

Look at the socket? Are there two contacts? If so, 7528 (or 1157, same thing) is correct (and that's what the parts catalog will show). However, in the case of my 1991 740, there is only one contact in each socket. If that is the case use an 1156 bulb.
I spoke with an expert Volvo mechanic and he told be Volvo used two different tailight assemblies, a Hella and another one I can't recall by name. He said there appears to be no rhyme or reason as to what car has what, and this is the reason for the discrepancy in the proper bulb. The only way to know for sure what you have is a visual inspection on the unit.

try over riding the starter relay on the fender ,it has one there right?. dont go to a mechanic yet. the engine aint seized. if it doesnt have this relay then i would get the alternator tested. if you want to test it yourself it can be costly for the right equip. autozone usually tests for free. i dont know were you live so if theres not an autozone. let me know if you cant get it tested.

Had the exact same problem with my 240 wagon. There is a temperature sensor up near the manifold on the drivers side of the engine. This is not the temp sensor that feeds the dash gauge, but one that tells the engine control module whether you are starting hot or cold. Mine was cracked, so the engine computer would get a cold start signal even after the engine ran warm, and would flood. This can be a difficult problem to diagnose and an expensive one when mechanics start swapping parts.
You cannot see this sensor, but you can feel it (when the block is cold, please) right under the exhaust manifiold. A replacement is about $80 plus labor. Even my very experienced Volvo mechanic overlooked it. But the car would start and run fine, then leave me stuck when I tried to restart it. After calling AAA for a tow, the temp sensor would reset, then the car would start normally.
Cheers. The 240 is a great car - I ran mine up to 235,000 miles; now I have a 740 with the same engine.

p0442 is not a volvo read code? converted to volvo it would read ecm 4308 small fuel leak/ start by replacing the gas cap and resetting it all/volvo scan tool can run a instant pressure test and see if it pass or fail after passing run car 200 miles before emission test to complete drive cycle

First, all these mechanics that you took your car to, did they have the full Volvo diagnostic software? In other words, were they able to access ALL computer systems that the lights were on for? If not, take your car to the Volvo dealer or a shop that has the proper software.
If the alternator does not charge or drops out while the engine is running, it will cause ALL the warning lights to come on.
Did you try adjusting the dash light dimmer control?
